SPEED IVIECHANISM.

SPECIFICATION forming part of Letters Patent No. 710,271, dated September 30, 1902. Application filed June 21, 1902. Serial'No. 112,666. (No model.)

To all wiz/m, it may concern:

Be it known that we,J AMES SAMUEL HEATH, a British subject, and LAWRENCE HEATH and ERNEST BASEMAN, citizens of the United States, all residing at Macedon, in the county of \Vayne and State of New York, have in-y tributing mechanism; but it will be obvious.

that it could equally aswell .be applied to the seed or grain distributer, or, in fact, to

2o any form of mechanism wherein change of speed is required.

Our invention consistsin the construction and combination of parts now to be described in the specification and as finally pointed out in the claims.

Referring to the drawings, wherein the same parts are designated by the same characters of reference in all the views, Figure 1 shows the hopper of a seeding-machine or grain-drill 3o with our invention vapplied thereto, certain of the parts, including the shifting strap, being broken away tovshow other parts more clearly. mechanism. Fig. 3 is an end view thereof.

3 5 Figs. 4: and 5 are details showing in side view and in section the adjusting means for the pivoted pawl; and Figs. 6 and 7 are details showingin end and side view, respectively, a modified and preferredform of frame or 4o hanger forthe'upper gears.

The fertilizer-wheels and connected parts are attached to the hopper 1 and may be of any desired or preferred construction, being operated in the customary manner from the fertilizer or driven shaft 2. Fast upon the driven shaft 2 is the gear 3, inclosed within a frame or case 4, pivotally mounted upon the shaft 2, and which also contains and supports the double gear 5 6, mounted on its 5o stud within the frame or case in such man- Fig. 2 is a side view of the speedY ner that the smaller member 5 of the gear 5 6 meshes into the gear 3 upon the shaft 2, and whereby the required motion is imparted to the shaft 2 when the larger member 6 of the double gear 5 6 is actuated in the man- 55 l ner now to be described.

Motion is communicated from the driving shaft or axle 7 by means of a double gear 8 9, fast thereupon, which double gearmeshes by means of the smaller member 8 into the 6o gear 14, and by means of the larger member 9 into the gear 10, the gears 14 and 10 being mounted, respectively, by their studs 31 and k30 in a case or frame 12, which is pivotally -mounted upon theaxle 7 and surrounds and 65 contains also the double gear 8 9 upon the axle 7. The studs 31 and 30 of the gears 14 and 10 project from the side of the case 12 sufficiently far to permit of the external gears 13 and 11, respectively, being secured there- 7o to. These gears 13 and 11, by reason of the ngearing described as contained Within the case 12, are constantly driven at different rates of speed when the axle 7 is rotated, the gear 13 being the slow-speed gear and 75 the gear 11 the high-speed gear. These gears are so positioned and located upon the outside of the case 12 that when the said case is pivotally turned about the axle 7 one or the other of them is caused to enter the case 8o 4 and mesh with and operate the larger member 6 of the double gear 5 6, or when the case is given still another position to be both out of engagement therewith. Adjusting means for this purpose are provided in the notches 15, formed upon the edge of the case 12. These notches 15 are shown in the drawings as being three in number and as adapted to be engaged by the spring-actuated pawl 16, pivoted at 17 to the hopper. When the 9o pawl 16 engages the lower notch`15, the gear 13 will mesh with the gear member 6, when in engagement with the upper notch 15 the gear 11 will mesh with the member 6, and when the pawl 16 is in engagement with the 95 middle one of the notches 15 the gears 11 and 13 will be both of them out of engagement.

In order to readily effect ithis adjustment of n the case 12, we have provided a simple and efficient means for operating the pawl 16. roo

The handle 2O is rigidly attached to the case 12 and has pivoted to it a lever formed with ahand or operating piece 2l and a curved extension 22, which lies in proximity to the pawl16 and passes under a pin 23, projecting therefrom in such manner that when the handpiece 21 is pressed by the operator the member 22 will disengage the paw] 16 from the notch 15 by reason of its engagement with the pin 23 on the said pawl. The case may be then shifted by the handle 20, so that the desired notch 15 will be brought into position to be engaged by the pawl 16, when the release of the handpiece 21 permits the spring-actuated pawl 16 to engage the notch, and the contact of the pin 23 thereon with the member 22 will restore the handpiece 2l to its original position. lIt is to be noted that the curved arm 22 is formed as in the arc of a circley having the axle as its center, which arrangement insures the constant and uniform engagement of the curved arm 22 with the pin 23 upon the pawl 16 as the case 12 is adj usted about the axle 7. This arrangement of adjusting and locking mechanism is most simple and convenient in operation, and it will be seen that the location of the unlocking-lever 21 22 upon the shifting lever 20 of the case 12 permits the case to be entirely manipulated with one hand. The pawl is formed in two pieces 16v and 18, the two parts being joined byadovetailed connection to insure rigidity and being provided with slots and a bolt 19 to permit of their necessary adjustment. (See Figs. 4 and 5.)

In Figs. 6 and 7 We have shown a simple and preferred modification of the frame 4, which consists in this instance of a single hanger with the double gear 5 6 journaled thereto. This frame or hanger is simpler, cheaper, and lighter than the double case and, moreover, permits the studs 30 and 31 on the case 12 to be made shorter, as no provision is necessary for the farther wall of the double case. Means'are also provided whereby the upper frame or case 4, with its contained gears, may be swung out of operative position at certain times, as when the hoes, disks, or shoes are raised, so as to stop the delivery of the fertilizer. An arm 28is fast upon the rockshaft 27 and is provided with a stud which engages in a slot in the piece 26 upon one end of the link or strap 25, the other end of which iis/connected in any suitable manner to the pivoted case 4, as indicated by dotted linesin Fig. 2. When the rock-shaft 2'7 is turned in the direction of the arrow, so as to raise the hoes, dac., in the manner well understood, the arm 28 is moved downwardly, and by reason of the engagement of its stud with the slotted piece 26 the link 25 is moved longitudinally in such manner as to swing the case 4 about the shaft 2 and to disengage the gear member 6 therein from the operating-gear upon the case 12. When the hoes, &c., are returned to their operative position, the rock-shaft 27 will be moved in the opposite direction and the case 4 restored to its normal position.

Our invention aords a sim ple and convenient form of speed mechanism that is both efficient and durable and one in Which the necessary adjustments canV be made with the utmost ease.
